I have flown quite a bit in the fixed shell Y seats on the 77W. If you can get a bulkhead or an exit row with a bit or a lot of extra legroom, then I think they are great. The standard seats are not bad, but I used to prefer not to "recline" them though. It has been quite a while. I don't think there is any way, shape, or form where the 3-4-3 is a better option.
